I realized that operating today in WPX that the temp was reading over 43 c and no fans. Manually turned them on. Reloaded firmware and still no fans when getting over 40 deg c. Ser no. 316. Ver. 2.38. I'll have to wait for Elecraft support but if anyone else has had this problem I would be interested in the fix.
